Description
The AmeriGlo Agent set is built around the same sight configuration the FBI selected for duty use on their Glocks, and it shows the moment you line one up. The front blade is a ProGlo-style post with a green tritium lamp wrapped in a bright orange ring, so your eye snaps right to it in daylight. When the sun goes down, three Swiss-made tritium lamps light up for a classic 3-dot picture that stays visible in pitch dark. If you've been running the polymer sights that came on your Gen 5, this is a night-and-day difference.
What Makes the Agent Sight Set Different
The standout feature here is the rounded U-notch on the rear sight. Instead of a square box cut, the U-notch funnels your eye toward the front post and makes centering the front sight feel natural and quick. Two green tritium lamps sit on either side of the notch with subdued black outlines, which keeps rear glare down so the orange front really pops. Folks who've tried both tend to prefer picking up the front sight through that U-notch, and it's a big reason these sights earned their reputation with law enforcement.
Fitting the Agent Set to Your Gen 5 Glock
This is the Gen 5 specific version, machined to the .200-inch front height and 6.5mm rear that matches current Gen 5 slides. It's designed to drop into standard Gen 5 models like the G17, G19, G26, G34 and G45. Install is straightforward with the right tools. A front sight tool handles the screw, and a sight pusher or brass punch takes care of the rear dovetail. Some rear dovetails run tight and may want a touch of fitting, which is normal territory when swapping metal sights onto any Glock.
Steel construction, a proven 3-dot layout, and that Federal-contract pedigree make the Agent a smart pick whether you're setting up a carry gun, a home-defense pistol, or just want sights you can actually see when it counts.

Frequently Asked Questions
Which Gen 5 Glocks does the Agent sight set fit?
It's cut to Gen 5 spec and fits standard-height Gen 5 models such as the Glock 17, 19, 26, 34 and 45 in 9mm. The front sits at .200 inches with a 6.5mm rear, matching current Gen 5 slides. Keep in mind these are standard-height sights, so they will not co-witness with a slide-mounted red dot on MOS pistols.
What makes the Agent sights the same as the FBI sights?
The Agent set is modeled after AmeriGlo's Federal contract sights, the same style selected by the FBI for their duty Glocks. That means the bold orange-ringed green tritium front and the rounded U-notch rear that helps you drive your eye to the front post fast. It's a proven setup that carried over from agency use to the general market.
How do the Agent night sights hold up in low light?
The three Swiss-made tritium lamps glow on their own and stay visible in complete darkness, so you get a full 3-dot picture at night without any batteries or charging. During the day, the orange front ring does the heavy lifting for quick pickup. It's a solid all-around answer for both bright range time and dim rooms.
Are these hard to install on my Glock?
Most people find the install straightforward with the right tools. You'll want a front sight tool for the screw and a sight pusher or brass punch for the rear dovetail. Some rear dovetails run tight and may need a little fitting, which is normal when putting steel sights on a Glock, so go slow and check your fit.
